BACKGROUND Technical Field

The present disclosure relates to transmission methods and devices inwireless communication systems, and in particular to a scheme and adevice for measurement in wireless communication.

Related Art

Application scenarios of future wireless communication systems arebecoming increasingly diversified, and different application scenarioshave different performance demands on systems. In order to meetdifferent performance requirements of various application scenarios, the3^(rd) Generation Partner Project (3GPP) Radio Access Network (RAN) #72plenary session decided to conduct the study of New Radio (NR), or whatis called fifth Generation (5G). The work Item (WI) of NR was approvedat the 3GPP RAN #75 session to standardize the NR.

In response to rapidly growing Vehicle-to-Everything (V2X) business,3GPP has started standards setting and research work under the frameworkof NR. Currently, 3GPP has completed planning work targeting 5G V2Xrequirements and has included these requirements into standard TS22.886,where 3GPP identifies and defines 4 major Use Case Groups, coveringcases of Vehicles Platooning, supporting Extended Sensors, AdvancedDriving and Remote Driving. At 3GPP RAN #80 Plenary Session, thetechnical Study Item (SI) of NR V2X was approved.

SUMMARY

Compared with the existing LTE systems, 5G NR has an outstanding featureof supporting more flexible Numerologies, which includes SubcarrierSpacing (SCS) and Cyclic Prefix (CP), and more flexible framestructures, such as of mini-slot, sub-slot and slot aggregation. Withsuch flexible numerologies and frame structures, various new businessrequirements will be better satisfied, especially in highly diversifiedvertical industries. A stricter payload balance control is a significantcharacteristic that differentiates V2X from traditional cellularnetwork, since effective payload control can reduce the probability ofbusiness conflicts and improve transmission reliability, which arecritical factors for successful V2X. In LTE V2X system, however, ameasurement mechanism for payload control is designed based on a singleNumerology, namely, 15 kHz SCS, normal length of CP and 1 ms of subframelength, making it impossible to meet the requirement of more flexibleNumerology of 5G NR V2X.
